Landfills in California face significant environmental scrutiny due to methane emissions and groundwater protection concerns. Marsh Canyon Sanitary Landfill must comply with state and federal regulations for landfill gas collection to reduce methane leakage, a potent greenhouse gas. Leachate management is also critical, as the facility's proximity to groundwater resources requires robust containment and monitoring systems. Community proximity and truck traffic are additional considerations, as Brentwood is a growing suburban area.
